Abstract
This paper addresses the investigation of hot spots identified during infrared thermal analysis of the thermal test dice in a multichip module and the physical analysis procedures utilized to determine the nature of the mechanism. An apparent enhancement of thermal conductivity in delaminated regions of non-uniform die attach adhesion is detailed.
